act description thereof.

Our invention relates to devices for locking vehicle-seats to their supports, and will be fully described hereinafter. a

In the drawings, Figure l is a section of a wagon seat and a portion of a body of a Wagon with our improved locks in operation. Figs. 2 and 3 are respectively a side View and H cross-section of a portion of a seat-riser and of Fig. 4 is a detail."

a wagon-body with our invention attached.

A Aareportions of the side bars of a wagonbody, and B B are cleats or rails attached securely to the side bars. p

O O are the seat-risers, having cleats G G running along their lower inner edges, and to these cleats U G we s'ecurcthe lugs D D,each having a vertical hole,d, for the shanks of the locking-teeth, which fit loosely therein, and

- also having a cut-away portion, 01, to admit the lower end of a brace, E, between it and the cleat on the seat-riser, where both that end of the ing and the brace E are secured to the riser by thesame bolt. A perforation, c, admits a securing-screw to the other end of the lug D. The braces E not only serve to steady and support the wagon-seat,but assist in keeping all the parts in place by taking up a part of the strain from the seat and from the wagonbody and risers, and the lugs D, as shown, are constructed with especial reference to the brace, whereby the required strength is obtained withoutundne or extra projection within the wagonbody, and without the necessity of an extra perforation in the lug to secure it to the brace and to the wagon-body. After the shanks f of the, teeth F have been passed up through the holesd in the lugs D, an tccentric, G, having a handle, G, is pivoted by abolt, q, to the flattion that portion of the eccentric which is nearest the pivot-bolt y will rest upon the top of the lug D, and consequently the tooth will be dropped to its lowest-position, as shown in dotted lines in Figs.2 and 3, and when in. this position its shank may be .freely revolved. Therefore, to adj usta seat havingour improved IOGkSJZO its position on a wagon-body, the hair dles of the eccentrics must be lifted to the position shown in dotted lines and turned until the hooks point to each other or assume the position with reference to the side bars, A, illustrated in dotted lines, Fig. 3. The seat having been placed in position, the hooks should he turned under the rails and the levers depressed until theyare in the position shown in -full lines, Fig.2-that is, with the thickest portionof the eccentrics'wedged between the pivot-bolts and 1ugs-where' they will be securely held until the levers or handles G are lifted by a slight upward pull.

Vi e are aware that we are not the first to secure wagon-seats firmly in place by means of a toothed shank passing through a hole in a lug secured to the Wagon-body, the tooth being adapted to be turned under a projection on the wagon-body and'locked in place by an eccentric; but in all such devices, so far as known to us, the cam and its handle are incapable of motion except in a vertical line, which necessitates separate action to turn the locking-hook in or out of position; whereas in our device the whole action and adjustment can be accon1- plished by one handin a single operation and the locking'hook or shanked tooth automatically adjusted by the horizontal movement of the handle of the eccentric, thereby saving time and labor andenabling one person to ac squared on opposite sides, and a bifurcated cam or eccentric, G, the inner sides of which fork bear directly against the squared portion of the shank f, whereby the locking-tooth may In testimony that We claim the foregoing we beturned in or out and locked or unlocked by have hereunto set our hands this 10th day of a single operation of the cam-handle, as set May, 1881. forth.
